Energy Saving Tips
Introduction
Every home is a complex energy system - from hot
water and air conditioning, to cooking, lighting, heating, refrigeration
and entertainment.
Energy management - the efficient use of energy
- is often the result (or a part) of sound energy conservation
practices. But conservation alone does not always reflect good
energy management, especially where electricity is concerned.
Because alternating current (AC) electricity can’t
be stored, the time when it is used becomes important. For example,
using electricity during off-peak hours does not conserve electricity,
but is a wise management of this energy resource.
According to the U.S. Council for Energy Awareness,
the average family spends about $2,000 to $4,000 each year directly
for energy. By applying the following energy guidelines and appliance-use
tips, you could easily save big bucks annually.

Home Heating Energy Savers
With the uncertainty of sufficient oil supplies,
you may be searching for other means of heating your home. There
are several affordable electric alternatives.
Electric Thermal Storage or ETS works like a thermos,
allowing the storage of heat until needed. Heated with low cost
off-peak electricity, the ETS unit releases this stored heat whenever
needed to maintain the level of comfort desired. During off-peak
periods, electric heating elements surrounded by heat storage
bricks are energized. The bricks, along with the super-efficient
insulation, help to keep the heat inside the unit. The room’s
thermostat controls a small fan located inside the heater. When
the thermostat calls for heat, the fan draws cool room air into
the unit, circulates it around the heated bricks and returns it
into the room.
There are also a variety of heat pumps. A heat
pump is a mechanical device that can transfer heat. In the winter,
it transfers heat into your home; in the summer, it takes heat
out of your home.
An air-source heat pump uses air to move heat
from one location to another. In the summer, an air-source heat
pump works like an ordinary air conditioner, extracting heat from
inside your home and pumping it outdoors. In the winter, it reverses
itself and pumps heat into your house. That’s because even
very cold air contains heat. For example, 0 degrees Fahrenheit
air still contains 89 percent of the heat that 100 degrees Fahrenheit
air does.
A ground-source heat pump works just like an air-source
heat pump, but uses a transfer fluid to move heat. Ground-source
heat pump systems have the greatest potential for efficient and
economical operation since ground temperatures remain fairly constant
most of the year. There are two types of ground-source heat pumps:
A groundwater heat pump uses groundwater; an earth-coupled heat
pump uses a sealed loop of buried pipe containing a water and
antifreeze solution.
A dual fuel system is a combination of a heat
pump with an oil, gas or ETS furnace as a back up. A house is
heated by the heat pump alone until the outside temperature drops
below a certain level or a peak electrical use period occurs.
At this point, the heat pump automatically shuts down and the
furnace kicks in. This arrangement allows each fuel source to
take advantage of its most efficient characteristics.

Water Heater Energy Savers
In the average American home, the water heater
is the second biggest energy user, accounting for about 15 percent
of the energy you use. Even so, electric water heaters are by
far the most efficient water heating devices available.
Here are some ways to save energy:
Water heaters have adjustable thermostats. If
you have a dishwasher without its own water-heating element, 140
degrees Fahrenheit is needed. But be careful of scalding at this
temperature. If your water heater only services bath and kitchen
needs, 110 degrees Fahrenheit will work. On older water heaters
with less insulation, for every 10 degrees Fahrenheit you lower
the temperature, you save 6 percent of your water heating energy
by avoiding less heat loss through the skin of the unit.
If your water heater was made before 1987, wrap
insulation or a water heater blanket (available from hardware
stores) around your water heater. Be sure not to block off vents
or any thermostat controls or you may create a safety hazard.
Proper insulation on your water heater can save up to $20 per
year and return your initial investment in one to three years.
(Water heaters built after 1987 are already well-insulated.) Do
not wrap gas- or oil-fired water heaters.
To minimize heat loss in water pipes, locate your
hot water storage tank as close as possible to the area of most
frequent hot water use (kitchen or bath). For extra protection
against heat dissipation, insulate your hot water pipes.
Fix that drip! Dripping, leaky faucets
are more than just annoying; they’re expensive. A faucet
that drips one drop per second can waste 2,300 gallons of water
per year as well as the electricity needed to heat it.
If you’re thinking of buying a new water heater, look into
a high-efficiency water heater. It may cost more initially but
you’ll save money over time.

Air Conditioner Energy Savers
Today, over 70 percent of Sussex Rural Electric
Cooperative homes have air conditioners. But they use a large
amount of electricity. On an average summer day, air conditioners
provide enough cold air to produce 16 trillion ice cubes!
Air conditioners are evaluated in two ways- by
cooling capacity and by seasonal energy efficiency ratio (SEER).
Cooling capacity is the amount of heat (measured in Btu) that
an air conditioning unit can remove from the air in one hour.
A 12,000 Btu air conditioner will remove 12,000 Btu of heat from
an area every hour. As a general rule, 18 Btu removed per hour
will cool about one square foot of a normal home.
SEER is the number of Btu of heat that one watt
of electrical energy will remove from the air in one hour. You
should try to buy a unit with an SEER of 10 or above.
Here are simple ways to make your window-unit air conditioner
more efficient:
To cool your house efficiently, your air conditioner
has to be cool. So try to keep it in the shade. An air conditioner
exposed to direct sunlight will use 5 percent more energy than
a shaded one.
Turn the air conditioner off when you leave the
house for several hours or more.
Set your home’s thermostat as high as possible
- the recommended minimum energy-efficient summer temperature
is 78 degrees Fahrenheit.
Care for the coils. If they’re dirty, dusty
or clogged with leaves, vacuum them with your household vacuum
cleaner. If the attachment on the vacuum won’t fit between
the coils, reverse the airflow and blow the dirt away instead.
Don’t forget the filters. A clogged filter
can cause an air conditioner to use up to 5 percent more energy.
Permanent filters should be cleaned according to the manufacturer’s
instructions. Disposable filters should be replaced at least once
at the beginning of the cooling season.
Be sure to seal any cracks between the unit and the window.

Lighting Energy Savers
It is estimated that about 20 percent of all the
electricity used in the U.S. goes into lighting. Although lighting
your home probably doesn’t account for 20 percent of your
energy dollars, it still provides a very large area to implement
cost-cutting energy measures.
For example:
Long-life incandescent light bulbs can be less
energy efficient than regular ones. They easily cost more in extra
energy than they save on replacement bulbs because their “trick”
is that they save energy by emitting less light than their regular
counterparts. Unfortunately, you end up turning on another light
and actually use more energy! Before buying light bulbs, check
out the “lumens” rating on the package for actual
lighting levels.
Dust on a light bulb can reduce the light it gives
off by 10 percent and make it seem that you need a higher wattage
bulb.
A white wall reflects 80 percent of the light
that hits it, a black one just 10 percent. The more light the
wall reflects, the greater the chance the light can be “recycled”
by striking the wall, bouncing off and illuminating the room.
Opening curtains during the day will save lighting
energy. Direct sunlight is 100 times brighter than light from
a strong reading lamp.
Switch to compact fluorescent bulbs. They combine
the versatility of regular incandescent bulbs (they come in all
sizes and shapes) with the low energy consumption of fluorescent
lamps. Compact fluorescent lights give off the same amount of light as incandescent bulbs,
but use 75 percent less energy. They also last more than 7,500
hours - 10 times longer than incandescent bulbs.
If you replace an incandescent bulb with a compact
fluorescent one, you’ll save the equivalent of 600 pounds of
coal that would otherwise be burned to power the incandescent
bulb over its useful life.
Compact fluorescent light isn’t like the
cool greenish-white light you’re used to seeing in offices
and schools. It’s closer to the “warmth” of
incandescent bulbs. Compact fluorescent lamps use an electronic ballast
and come on instantly, but they don’t “hum”
or flicker like regular fluorescent lights.
Compact fluorescent bulbs are expensive, costing $10
to $25 per bulb. But they use so little energy that they’ll
pay you back the purchase cost in a reasonable time.
Install compact fluorescent bulbs in lights that you
leave on more than five hours a day.
Top
Refrigerator Energy Savers
Your refrigerator requires more energy than any
other household kitchen appliance. In the U.S., refrigerators
use 7 percent of the nation’s total electricity. These tips
can help your “fridge” run more efficiently:
Keep your refrigerator and freezer at the right
temperatures. Even if they’re only 10 degrees Fahrenheit
colder than necessary, your energy consumption will go up an amazing
25 percent! Set your refrigerator between 38 and 42 degrees Fahrenheit
and the freezer between 0 and 5 degrees Fahrenheit.
Make sure the door is tightly sealed. Check the
gasket (rubber seal) for cracks and dried-on food. One easy way
to test the seal is to close the door on a piece of paper and
then try to pull the paper out. If it slides out easily, it’s
a sure sign cold air is escaping. Another way to check is the
flashlight test. Place a lighted flashlight inside the refrigerator,
close the door and turn out the lights in the room. A leak along
the seal will show dramatically.
Keep the condenser coils clean. Brush or vacuum
them at least twice a year to make them more energy efficient.
“A full fridge is a good fridge.”
It’s better to keep your refrigerator about three-quarters
full because food retains cold better than air. But don’t
overcrowd – cold air needs to circulate.
Put a lid on any liquids. This will reduce humidity
levels inside the refrigerator, shorten the defrosting cycle and
keep food moister longer.
Move food you need to defrost from the freezer
to the refrigerator a day before you need it. This way, the frozen
food helps to cool the refrigerator as it thaws, and gives the
refrigerator’s motor a break.
Top
Oven/Microwave Energy Savers
Every time you open your oven door during cooking,
you lose 25 degrees - or more. Microwaves use around 50 percent
less energy than conventional ovens; they’re most efficient
for small portions or defrosting. Stovetop cooking is more efficient
for larger items. Pressure cookers are considerably more energy
efficient than regular ovens.
Here are some other energy saving oven/cooking
tips:
Use an oven thermometer to test the thermostat
in your oven to be sure it measures temperatures accurately. Chances
are, it doesn’t. If it doesn’t, replace the thermostat
or use an oven thermometer as an accurate gauge.
Check the reflectors under your stovetop burners.
The cleaner they are, the better they’ll reflect heat. The
best reflectors on the market can save as much as 33 percent of
the energy used when cooking on top of the stove.
Inspect the seal on the oven door for cracks.
Even a small gap allows enough room for a lot of heat to escape.
Clean self-cleaning ovens right after use, to
take advantage of residual heat.
And as obvious as it sounds, don’t operate
the oven with the door open.
Top
Dishwasher Energy Savers
A load of dishes cleaned in a dishwasher requires
37 percent less water than washing dishes by hand, if you leave
the water running. But dishwashers commonly use water heated to
140 degrees Fahrenheit, which is hotter than any other water used
in your home.
Dishwashing is a surprisingly energy-intensive
activity, which leaves lots of room for conservation practices.
For example:
More than 80 percent of the energy your dishwasher
uses is for heating water. Wash only full loads for increased
energy savings. Also, use short cycles for everything but the
dirtiest dishes.
If your dishwasher has an air-dry setting, choose
it instead of the heat-dry setting. You’ll knock at least
15 percent (and in some cases as much as 50 percent) off the energy
your automatic dishwasher uses. If there’s no air-dry setting,
turn off the dishwasher after its final rinse and open the door.
The dishes will dry without using any extra electricity.
Rinse dishes with cold water before loading them.
Install your dishwasher away from your refrigerator.
The dishwasher’s heat and moisture make the fridge work
harder. If you have to put them next to each other, a sheet of
foam insulation can minimize the impact.
Top
Washing Machine Energy Savers
The average American home washing machine is used
416 times a year. Washers and dryers can account for as much as
25 percent of the electricity you use in your home (including
the hot water for the wash).
Save energy by using the right laundry detergent.
With today’s fabrics, many lightly soiled clothes can come
clean even in cold water.
Experiment with cold water wash and rinse cycles.
For most clothes, the results will be as good as a hot water wash
and warm rinse and you’ll cut your energy use in half.
Each wash cycle uses 32 to 59 gallons of water.
That’s as much as two showers. So set the water level in
the washing machine to suit the size of the load – you’ll
save both water and energy.
Try washing on a “delicate” setting
instead of “regular.” The motor won’t have to
work as hard and will use less electricity.
Top
Clothes Dryer Energy Savers
The energy efficiency of a clothes dryer depends
on unobstructed air circulation around your clothes. So keep the
lint filter and exhaust hose clean. Best advice: clean the
lint filter after each load.
Dry full loads, but don’t overload your
dryer. Clothes need room to tumble so air can circulate around
them.
If your dryer has a moisture sensor setting, use
it. It will shut off the dryer automatically when clothes are
dry.
Don’t add wet items to a load that’s
already partly dry.
Dry heavy and light fabrics separately. This way,
all the clothes in the load will be done at once.
Don’t leave the dryer on longer than necessary.
Often, clothes are already dry, but no one runs down to the basement
to shut the dryer off. Over-drying clothes wears down fabric in
addition to wasting electricity.
In the winter, vent your dryer inside. Use old pantyhose as a
filter over the exhaust vent. You can also install a magnetic
louvered vent to help prevent excess heat loss.
Try a clothesline — it’s old-fashioned
and energy free.
Top
Ironing Energy Savers
A hand iron consumes as much energy as ten 100-watt
light bulbs when it is on. These steps can increase ironing efficiency:
Buy “no-iron” sheets and clothing
and use the permanent press cycles on your washer and dryer.
Remove your clothing promptly from the dryer and
hang carefully. Many items won’t require ironing.
Iron large batches of clothing at one time.
Iron low-temperature fabrics first to reduce warm-up
time.
Prevent scorching and wasting energy by not overheating
the iron.
Hang clothes in the bathroom while you shower
- the steam often smoothes wrinkles.
If interrupted when ironing, be sure to turn off
your iron.
Top
Door & Window Energy Savers
About 15 percent of the energy you use for heating
your home goes to warming up air that leaks in through cracks.
In heating terms, the gaps you can find around windows and doors
are equivalent to a 3 x 3-foot hole in the wall. Caulking and
weather stripping are two simple weapons you can use to stem this
“great escape”.
Caulk cracks that have no moving parts, such as
places where a wall meets the outside edge of a window frame.
Weather stripping uses cleverly designed strips
of felt, rubber, plastic or metal to fill spaces between the frame
and doors or windows. To determine where weather stripping is
needed, hold your hand to various spots around window and doorframes
some evening when your house is at least 20 degrees warmer than
the outdoors. If a draft is felt, weather stripping is needed.
Seal leaks around electrical switches and outlets.
Gaskets are available that fit behind the switch plates and keep
out a surprising amount of draftiness. You can install them yourself
with just a screwdriver. There are no electrical connections between
the plate screw and the circuit. But to be entirely safe, you
can remove the proper fuse or turn off the circuit breaker before
you start installation.
Top
Window Energy Savers
Storm windows are the easiest way to reduce heat
loss from your home. Window glass is only about one-eighth inch
thick and conducts heat away from your living space. A storm window
traps air between the glass and itself. This “dead air”
space acts as insulation.
If you want storm windows on your home, but don’t
want the expense of installing conventional ones, you can make
plastic windows which can be applied to the inside of your windows.
On sunny winter days, open drapes to let the warm
sunlight in; close them on hot sunny summer days to keep heat
out.
Install white blinds on the south- and west-facing
windows to keep the sun from broiling your house in summer.
Top
Fireplace Energy Savers
The value of a fireplace as a heat source is deceptive.
A burning fire causes a large flow of air through the hearth and
up the chimney. The source of this flow is usually air in the
house that has already been heated by a furnace. So, while a fire
warms the immediate area through radiant heat, it is cooling the
rest of the house by drawing out warm air through the chimney.
If the difference between the indoor and outdoor air is 30 degrees
or more, you suffer a net heat loss.
Here are ways to make your fireplace more energy
efficient:
When using your fireplace, lower the house thermostat
to 50 degrees.
Close off the room that has the fireplace from
the rest of the house.
Install an efficient, freestanding, airtight wood
or coal stove in your fireplace.
Install an air duct that allows outside air to
be the source of air for combustion.
Close fireplace dampers when not in use to prevent
heated or cooled air from escaping up the chimney.
Top
Thermostat Energy Savers
Wise use of thermostats can reduce your heating
and cooling by up to 30 percent!
For example:
During winter, you can save as much as 3 percent
of the energy your furnace uses simply by lowering your thermostat
1-degree Fahrenheit (if it’s set between 65 and 72 degrees).
In the summer, the process is reversed. You can
save 5 percent of the energy used by your air conditioner for
every degree you raise the thermostat (if it’s set between
70 and 82 degrees).
Keep your thermostat under control - 68 degrees
Fahrenheit in winter during the day, 55 degrees at night. In summer,
turn it to 78 degrees.
Check the temperature with a thermometer to make
sure your thermostat is representative of the rest of the house.
If it’s located in a drafty or sunny spot, you may be getting
false readings and wasting energy.
Plug the hole in the wall behind the thermostat
with caulking or sealant.
Top
Shower Savers
If each member of a family of four takes a daily
five-minute shower, the family will use more than 700 gallons
of water every week - a three-year supply of drinking water for
one person. Here’s how to shave your water use and save
electricity at the same time:
To cut shower water use by 50 percent, just replace
your conventional showerhead with a “low-flow” model,
available from any hardware store.
The U.S. Department of Energy reports that installing
a low-flow showerhead cuts water heating costs by as much as 50
percent.
With a low-flow showerhead, four family members
taking five-minute showers each save 14,000 gallons of water a
year. So, if only 10,000 families installed low-flow showerheads,
we could save 140 million gallons.
Top
Insulation & Caulking Savers
Reducing heat loss in winter and heat gain in
summer are the most important considerations in managing energy
in the home. The greatest loss is through the ceiling and roof.
Conveniently, this is also the easiest area in which to install
adequate insulation.
Exterior walls and floors over unheated areas
are also important to insulate. You can probably reduce your energy
loss by 20 to 30 percent with additional insulation and as much
as 50 percent if your home has no insulation.
Recommended R-Values:
- R-30+ in ceilings
- R-19 in floors over unheated spaces
- R-19 in exterior walls
To stop drafts, try caulking!
Every home has gaps where different types of building materials
meet. By blocking these gaps, caulking can make your living space
more comfortable.
Get the most blocking power
possible and do the job right the first time. Buy a silicone sealant
with a long life span.
Install electrical outlet
gaskets to stop heat losses on the exterior walls of your home.
Folks with modular homes should also install these gaskets on
the walls where the pieces join. To be entirely safe you can turn
off your circuit breakers before beginning this project.
Cover hot-water pipes with
insulation where they run through unheated basements, attics and
crawl spaces. Also cover heating and air conditioning ducts with
insulation in these locations.

Other Energy Savers
Aside from the obvious energy users - domestic
use appliances, water heaters, space heaters, air conditioners
and pool pumps - there are other energy “vampires.”
An article from a recent Discover Magazine sited, “a study
performed at Lawrence Berkeley Labs [indicated] that five billion
watts of energy - roughly the amount produced by five power plants
- leak from appliances in U.S. homes every year.” The article
continued by pointing out that cable boxes use 20 watts of power
when plugged in but turned off - and 21 watts when in use. TV’s
consume five to 10 watts per hour when turned off.
Here are a few easy to apply tips that can help
you stop this drain on your wallet:
If you have a seldom-used tv/vcr combination,
unplug them. You save 43¢ per month on each combination.
If the package includes a small dish receiver, the savings per
month jumps to $2.15!
Look around your home. Electronic exercise equipment,
fax machines, stereos and computers all use energy when turned
“off”. If the plug is readily accessible, unplug them
when not in use.
All these small things can really add up –
to substantial savings over a year.
